Children’s simethicone dosage
Every chart below is transcribed from a real FDA drug-facts label, and grouped by the strength printed on the bottle. We calculate nothing.
Check the strength on your bottle first
The same medicine is sold at more than one concentration, and a chart is only correct for the bottle it was printed on. Find the “active ingredient” line on your package and match it to the heading above a chart below. If it does not match any of them, use the chart on your own box and ask a pharmacist if it is unclear.
20 mg per 0.3 mL
On the bottle this reads “Active ingredient (in each 0.3 mL) Simethicone 20 mg”.

Frequently asked questions
How much simethicone can I give my child?
Read it off the chart for the bottle you are holding, above. There is more than one strength of children's simethicone on sale, and each has its own chart — that is why this page shows them separately rather than giving one number. Dose by weight where the chart offers weight; the label itself says to use weight if you know it, and age only otherwise.
Why does the chart say "ask a doctor" for babies under 2?
Because the label does. The FDA drug-facts chart stops at the youngest age the product was approved to be self-administered for, and below that the manufacturer directs you to a clinician rather than printing a dose. We reproduce that row exactly and do not fill it in — a paediatrician dosing an infant is working from weight and a clinical picture that a chart cannot carry.
Can I use a children's chart with an infants' bottle?
No, and this is the mistake that causes real harm. The same drug is sold at different concentrations: infants' ibuprofen is 50 mg per 1.25 mL, children's is 100 mg per 5 mL. Reading one chart against the other bottle gives the wrong amount of medicine. Check the "active ingredient" line on your bottle against the strength shown above each chart here.
Can I use a kitchen spoon to measure it?
No. Use the syringe or cup that came with that specific product — labels say so explicitly, and household spoons vary enough to matter at these volumes. If the dosing device is lost, ask a pharmacist for one rather than estimating.
Where do these numbers come from?
Each table is transcribed cell for cell from that product's FDA drug-facts label on DailyMed, linked under every chart. We calculate nothing and we merge nothing across products.
